[Raak] If you've been in Norwich more than a year or two and it still doesn't have any culture, it's probably your own fault. If the people who like a certain thing always go to some other place to get it, they perpetuate the situation in which there's a market for that thing in that other place and none in the place they come from. Therefore, people in Norwich who like a certain kind of culture should never leave it, and they'll thereby coerce the place into being the sort of place they like to be in.
(It also helps if you kill off everyone who actively opposes the sort of thing you like.)
